A catalytic process and device for conversion of liquid or gas carbonaceous matter (6) to a mixture containing hydrogen H2 and carbon monoxide CO is disclosed. The resulting mixture is accompanied by methane CH4 and ethylene C2H4 and the conversion is achieved by a partial oxidization of the carbonaceous matter with the elementary oxygen O2 content in a gas oxidant added to the carbonaceous matter. The carbonaceous matter and gas oxidant come into contact with a catalyst comprising dispersed nickel oxide supported by a refractory for which the melting point exceeds twelve hundred and fifty degrees centigrade. The partial oxidization takes place in a temperature range of between six hundred degrees centigrade and one thousand degrees centigrade.

La présente invention concerne un processus catalytique et un dispositif pour convertir une matière carbonée liquide ou gazeuse (6) en un mélange contenant de l'hydrogène H2 et du monoxyde de carbone CO. Le mélange résultant est accompagné par du méthane CH4 et de l'éthylène C2H4 et la conversion est réalisée par l'intermédiaire d'une oxydation partielle de la matière carbonée avec l'oxygène élémentaire O2 contenu dans un oxydant gazeux ajouté à la matière carbonée. La matière carbonée et l'oxydant gazeux viennent en contact avec un catalyseur comprenant de l'oxyde de nickel dispersé supporté par un réfractaire pour lequel le point de fusion dépasse mille deux cent cinquante degrés Celsius. L'oxydation partielle s'exécute sur une plage de températures comprises entre six cents et mille degrés Celsius.
